Together AI

If you want to run, fine-tune, and deploy top open models in production without getting locked into closed ecosystems, Together AI is built specifically for that.

Much like OpenRouter and Novita AI, it pulls together a massive library of multimodal architectures under a single OpenAI-compatible endpoint. But here is the real kicker: Together AI runs the entire compute stack itself. Instead of just reselling access, they tune proprietary system kernels and attention mechanisms, backed by dedicated physical clusters, secure code sandboxes, and end-to-end post-training pipelines.

Here is what powers the platform under the hood:

• Serverless and Batch Inference: Fast, on-demand token execution for open-weight systems covering text, code, image, video, and speech. Run reasoning and multimodal heavyweights from DeepSeek, Qwen, GLM, Kimi, MiniMax, Gemma, and Llama, or throw massive workloads into asynchronous batch queues.
• Generative Media and Dedicated Endpoints: Dedicated instances and custom container runtimes tuned for video, audio, and visual generation, running models from FLUX, Seedance, Kling, Sora, Veo, and Whisper.
• Together Link Agent Gateway: A local proxy and routing tool that connects open models straight to coding agents like Claude Code, Codex, and desktop environments—intelligently routing simpler tasks to fast open models to slash API bills.
• Model Shaping and Fine-Tuning: Built-in workflows for supervised fine-tuning, LoRA adaptation, Direct Preference Optimization, and evaluations on large base checkpoints without the headache of managing raw machine nodes.
• Compute and Execution Environments: High-performance NVIDIA GPU clusters, managed storage with zero egress fees, and sandboxed code execution environments ready for agentic workflows.

Together AI delivers predictable, low-latency execution and complete operational control for production AI stacks.
